Materials Data on Rb4UC3O11 by Materials Project

Rb4UC3O11 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.28 Å. In the second Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.94–3.38 Å. U6+ is bonded in a distorted hexagonal bipyramidal geometry to eight O2- atoms. There are two shorter (1.85 Å) and six longer (2.45 Å) U–O bond lengths. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.26 Å) and two longer (1.32 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.27 Å) and two longer (1.32 Å) C–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to four Rb1+ and one U6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+, one U6+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one C4+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to four Rb1+ and one C4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+, one U6+, and one C4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+, one U6+, and one C4+ atom.
